|Condition or disease||Intervention/treatment||Phase|
|Carcinoma Sarcoma Rhabdomyosarcoma Neoplasms Small Cell Lung Cancer Triple Negative Breast Cancer Adenocarcinoma of the Pancreas Colorectal Carcinoma Gastric Adenocarcinoma Advanced Cancer Solid Tumor Solid Carcinoma||Drug: PEN-866||Phase 1 Phase 2|
Phase 1 will employ an adaptive model guided with overdose control principle to make dose recommendations and estimate the maximum tolerated dose (MTD).
Phase 2a begins once all patients treated in Phase 1 have been assessed for safety and the Safety Review Committee (SRC) has reviewed all safety data and recommends continuing with Phase 2a. PEN-866 will be evaluated using the recommended Phase 2 dose identified by the SRC at the conclusion of Phase 1 based on the safety, tolerability, pharmacokinetic, and pharmacodynamics profile of PEN-866 during Phase 1.

Intravenous administration of PEN-866
PEN-866 is a miniaturized conjugate that comprises an HSP90 targeting ligand linked to SN-38, the active metabolite of irinotecan. PEN-866 is available as a sterile lyophilized powder for solution for infusion.
- Incidence of Dose-Limiting Toxicities (DLTs) [ Time Frame: Patients will be followed for 28 days in Cycle 1 to determine the incidence of DLTs. ]In Phase 1, the Maximum Tolerated Dose (MTD) will be determined by assessing the incidence of DLTs and treatment related adverse events.
- Incidence of treatment related adverse events [ Time Frame: up to 28 days following the last treatment. ]In Phase 1, safety and tolerability will be determined by assessing the incidence of treatment related adverse events.
- Objective response rate (ORR) of tumors using RECIST 1.1 criteria [ Time Frame: From the date of first treatment through the date of first documented progression, assessed up to 18 months ]
In Phase 2, for each of the 6 tumor-specific cohorts, ORR will be estimated and presented with 95% confidence intervals based on the exact binomial distribution.
In addition, for each tumor-specific cohort, a Bayesian approach will be used to estimate the ORR and its 95% credible interval based on the posterior distribution. At completion of the study, within each tumor-specific cohort, the prior distribution will be updated with all data available from the evaluable patients at the MTD to obtain the posterior distribution of the true ORR.
- Maximum concentration of PEN-866 and its metabolites (Cmax) [ Time Frame: 1 Month ]Characterize the pharmacokinetic properties of PEN-866
- Area under the curve (AUC) of PEN-866 and its metabolites [ Time Frame: 1 Month ]Characterize the pharmacokinetic properties of PEN-866
- Half-life (t1/2) of PEN-866 and its metabolites [ Time Frame: 1 Month ]Characterize the pharmacokinetic properties of PEN-866
- Tumor response using RECIST criteria [ Time Frame: 2 Months ]In Phase 1, size of tumors by CT or MRI (RECIST)
- Radiographic progression free survival [ Time Frame: From date of first treatment/trial entry until the date of first documented progression or date of death from any cause, whichever is first, assessed up to 18 months ]In Phase 2, size of tumors by CT or MRI (RECIST)
- Overall survival [ Time Frame: From date of first treatment/trial entry until the date of date of death from any cause, assessed up to 18 months ]In Phase 2, time to death
